Canada battles illegal pot shops popping up all over: Montreal police have launched raids against illegal cannabis stores opened one day earlier by the self-proclaimed “Prince of Pot,” Marc Emery, and his wife, Jodie. Emery and his wife were among 10 people arrested in the recent raids. Police said that all but one person, who refused to sign the release documents, were allowed to leave on a promise to appear in court. Canada is moving to legalize marijuana, but it remains illegal. –Report by The Associated Press

Studies show big increases in older Americans’ marijuana use, drinking: I wrote last week on how fewer teens are using drugs or alcohol than at any point in the past few decades. Indeed, while anti-drug PSAs still encourage parents to talk to their teens about drugs before someone else does, two recent studies suggest there’s another high-risk population we should be worried about: our kids’ grandparents. The first study, based on over 45,000 responses to the National Survey on Drug Use and Health, isn’t the first to note that marijuana use is increasing rapidly among older adults. But it digs more deeply into the demographics of older Americans’ marijuana use, uncovering some interesting findings. –Report by The Washington Post’s Christopher Ingraham

The design-savvy DaVinci IQ vaporizer easily competes with market’s top vapes: Vaporizers have come a long way, and if the DaVinci IQ is any indication of things to come, I can’t wait to see what’s next. There are plenty of high-end portable vaporizer options on the market, including the Pax 3 and the Firefly 2, but a wide range of choices is something that’s great for the industry as a whole. Each model offers its own unique trade-offs, and DaVinci’s IQ brings an embarrassment of riches to vape consumers — riches such as a fully featured app, extremely good build quality and top-notch performance. If you’ve got money (or a cheap vape) burning a hole in your pocket, the IQ is a truly unique device that’s got a lot to offer any cannabis user. –Report by The Cannabist’s Chris Thomas
